Duodenojejunal intussusception due to an inflammatory fibroid polyp: a mimic of acute pancreatitis.

This report describes an extremely unusual cause of acute pancreatitis. It highlights the value of cross-sectional imaging, in the absence of alcohol and gallstone aetiology, to establish a diagnosis and direct management. Computed tomography (CT) revealed a duodenal jejunal intussusception. A benign inflammatory fibroid tumour, acting as a lead point, was surgically resected and the patient made an unremarkable recovery without further episodes of acute pancreatitis.
